Additional Information

The attractively priced Novex B series microscopes are high quality, robust biological microscopes for educational purposes and scientific research.

Viewing Head and Eyepieces

The microscopes of the Novex B series are available in three configurations: monocular, binocular or trinocular. The viewing head is mounted at 30º angle and can be rotated through 360º. Supplied with a WF 10x eyepiece(s), thesemicroscopes have a coaxial coarse and fine focus adjustment.

Revolving Objective Changer

All models are equipped with a reversed quadruple revolving objective changer with ball bearings slides for precise indexing (except for models 86.525, 86.541, 86.125 and 86.141). A five position objective changer can be supplied as an option.

Achromatic Objectives

There is a wide choice of Semiplan, Plan, Phase Contrast and ICS objectives (Infinity Corrected System).

Condenser

The Abbe condenser N.A. 1.25 can be centred and focused and is equipped with an iris diaphragm, filter holder and blue daylight filter.

Bright Field Illumination

Besides the built-in 6 volts, 20 Watt halogen illumination there are also models with LED illumination (3W) with rechargeable batteries for approximately 50 hours of usage and internal power supply.

The darkfield set consists of a special condenser with a large numerical aperture N.A. 1.20 (86.627), a DIN Plan 100x objective with iris diaphragm (86.521) and a cold light source (LE.5210 or LE.5211) with a flexible light guide (LE.5241). The indirect illumination method enables the microscope user to view the contour and structure of transparent and low contrast specimens on a dark background. One example of the use of this darkfield technique is living blood analysis (LBA). The LBA is a morphological research technique that enables observation of the shape of red blood-corpuscles (Erythrocytes). Anomalies in shape or function provide an approximate indication of possible pathological diseases.

Phase Contrast Set

The Novex B Series microscopes are available with several Zernike medium-dark phase contrast sets, complete with centring phase telescope and green filter. The models 86.410 to 86.491 have a Zernike phase contrast set with phase condenser N.A. 1.25 and a sliding phase plate containing a phase ring and an aperture for bright field. The sets are complete with a Plan phase S40x objective and 4x, 10x and S100x Semi-plan or Plan bright field objectives. For phase contrast an objective with a retardation plate and a condenser with a phase-ring is used.

Temperature Controlled Plate

Besides a phase set the models 86.525 and 86.541 have a specifically designed heat stage. The temperature of the stage can be adjusted up to 50ºC by a PID controller. The heater is mounted below the microscope stage and can only be ordered when purchasing a new microscope.

Camera and Video Set

The trinocular head phototube can be activated and de-activated. When it is activated the image remains visible in one eyepiece, which gives the maximum light intensity to the photo/video equipment. A separate brochure describes the digital and analogue photo/video camera solutions.
